SPECIFICATION forming part of Letters Patent `No. 587,424, dated August3, 1897.

Application filed December 17, 1896. Serial No. 616,026. (No model.)

To all whom t may concern,.-

Be it known that I, ROBERT A. BONINE, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Locks, of which thefollowing' is a specification.

According to my invention I provide an improved lock, latch, orfastening device especially adapted for doors, but it may be applied toboxes, windows, dac.

It is well known that doors often sag or settle and also often getsprung. I especially desire by my improvements to provide a fastener fordoors which will accommodate itself to any inequalities of this sort.

In the accompanying drawings, Figure lis a front elevation of myimproved fastener applied to a door. Fig. 2 is a view partly in frontelevation and partly in section. Fig. 3 shows a transverse verticalsection on the line 3 3 of Fig. 2. Fig. 4 is an inside view of the uppermember of the casing.

The lower member or ilat bottom plate A has apertures ct for thefastening-screws. It is formed with a lug d to receive a spiral springB, which enters a recess c in the handle C.

The upper member D of the casing is concavo-convex and it is providedwith a flange cl, having three apertures d for fasteningscrews and anaperture d2 for a screw d3, which connects the pawl E with the casing.This member of the casing is also formed with a boss d4, whichconstitutes a bearing for the pawl. The screw d3 passes through anaperture in the boss and also through the aperture cl2 and through oneof the apertures a in the lower member of the casing. The upper andlower members may readily be connected together, as shown in Figs. l and3.

The handle O projects through a central opening F in the upper member ofthe casing, which is flanged, as shown at f, to provide a long bearingfor the handle, permitting it to easily turn without shaking orwabbling. The handle is connected at its inner end with the bolt G,which is sector-shaped and is also rounded and beveled at its edge, asshown particularly in Fig. 3. It is also formed on its edge with aseries of ratchetteeth g, with which the pawl E engages. The

pawl, it will be observed, passes through an opening g in the casing,and it is provided with a weighted handle e, which causes the end of thepawl to engage with the teeth.

The keeper H is formed with a case or housing h for the end of the boltand with flanges having apertures h for the fasteningscrews. Normallythe parts occupy the position shown in Fig. 2 when the door is locked,the edge of the casing h coinciding with the edge of the casing of thebolt. Vhen in the position shown in Fig. 2, the bolt cannot be turnedback, because the pawl E prevents it from doing so. It can, however,readily be turned back when the pawl is elevated. Y The spring B tendsto press the bolt against the upper member of the casing, and it willhave a slight movement back and forth in line with the longitudinal axisof the lug a when positively moved. This allows the bolt to accommodateitself when the door is sprung or does not close tightly. Vhen this isthe case, the handle can be so moved as to allow the bolt to give alittle and permit the beveled or rounded edge to engage with the keeper.Then the bolt may be turned and the door may be thus fastened. Were itnot for this provision it might be difficult to cause the bolt to enterthe keeper.

As will be observed by reference to Fig. 2, there is a considerable freespace between the edge of the bolt G and the upper and lower ends of thecasing or housing h. Should the door sag or drop,the bolt may still beproperly operated, but will not enter into the housing quite so far, andthe pawl E, instead of entering the first tooth, as shown in Fig. 2,would enter the second or one of the succeeding teeth.

In practice there may be a variation of over an inch for amoderate-sized lock of this kind. Within the casing member D are formedtwo lugs m m', which limit the movement of the bolt G in bothdirections.

There are only four principal parts to this lock, only four patternsbeing required, thev spring and the screws and a small washern being theonly other parts used. A gravity-pawl is shown, and this is always usedwhen the lockis attached to an upright door. When the lock is used inother positions, a spring may be added to the pawl. The spiral springprevents rebounding and can easily be strengthened by spreading thespirals. Obviously the lock may be made right or left handed, so as tosuit both sides of the door.

I claim as my invention- A fastening device for doors, rbc., comprisinga sector-shaped bolt having rounded, beveled edges, and provided withteeth in its periphery, a handle secured to the bolt at its axis, aseries of teeth formed in the periphery of the bolt` the lower member ofthe casing having:r a lng formed with it which projects into a recess inthe bolt and handle, a spring contained in said recess and adapted tomove the bolt longitudinally of its axis, the upper member of the casinghaving a central opening and an elongated bearing-surface for thehandle, and a pawl pivoted to the casing and adapted to engage with theteeth on the bolt.

In testimony whereof I have hereunto subscribed my name.

ROBERT A. BONINE.
